Scout Space Booster

The Invid Scouts can attach themselves to a booster rocket sled for even greater speed. The use of the booster rocket attachment is reserved for high speed space combat, pursuit or interception, and to escape the gravitational pull of a planet. For example, the space booster enables the Invid Scouts to break free of Earth gravitation, becoming a transatmospheric vessel able to rocket into space and return like a space shuttle.
